Answer: D — Give cyclists plenty of room

When sharing the road with a bicycle, it is important to give cyclists plenty of room. This means leaving enough space between your vehicle and the bicycle so that you can safely maneuver without risking a collision. Speeding up and passing quickly (option A) may startle the cyclist and increases the likelihood of an accident. Driving closely behind the cyclist (option B) can also be dangerous as it makes it difficult for them to see you and for you to see them. Additionally, sounding your horn apprehensively (option C) can be startling and intimidating to bicyclists. Therefore, it is important to always give cyclists plenty of room when sharing the road to ensure the safety of both parties.
